CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 396,879, dated January29, 1889.

Application filed October 3, 1883! $erial No. 237,054. (No model.)

To all whom it may concern:

Be it known that I, ISAAC KLING, of Louisville, in the county ofJefferson and State of Kentucky, have in vented certain new and usefulIIHPI'OXTQHIGDIS in Car-Couplings; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form part of this specification, in which- Figure1 is a central longitudinal vertical section through a ca1.'-coupling,showing my improvements. Figs. 2, 3, and at are detail viewsillustrating the operation of the parts. Fig. 5 is a detail view of thejaw and its arm.

This invention relates to car-couplers of the pivoted-jaw type, and itsobject is to improve the locking devices of the jaw, it being animplovement of the coupler shown in my patent, No. 370,343, of September20, 1887, and in my application for Letters Patent filed August 1, 1888,and numbered serially 281,688. The object of this invention is to soconstruct the parts that the arm as it is swung inward during the act ofcoupling will positively lift the locking-tumbler and pass thereunderwithout any wedging action whatever. This object is accomplished by thehereinaftc1.'-described construction and arrangement of parts.

Referring to the drawings by letters, A designates the draw-bar; B, thelocking hook or jaw hinged on said draw-bar, and having a locking-arm,(3, adapted to enter the mouth of the draw-bar when the j aw is swunginward. D is the locking-tumbler pivoted in the throat of the draw-bar,and provided with a (lepei'lding link, E, by which it can be oscillated,and H is a lever-block, which may be pivoted in rear of tumbler I).These several parts are arranged and operate substantially as do scribedin my application above referred to.

The front. face of tumbler D is rounded in order to act as alink-support, as shown in Fig. 1, or it may have an angular shoulder,(1, formed in it, as shown in Figs. 2, 3, and 4. The end of arm 0 isangularly shouldered or reduced, as shown at c, and at the junction ofthe arm with the jaw is formed at the lower edge of the arm an inclinedshoulder or bevel, Z), which is adapted to engage an inclined shoulder,a, formed on the front lower lip of the draw-bar A. When the jaw isswung inward during the act of coupling, the incline l) engages shouldera just'as the shouldered end 0 of arm 0 comes beneath the angular faceof the tumbler D. Then, as the arm is forced farther around and inwardby the movement of the jaw, the incline b rides up on shoulder a,lifting the jaw and arm, and this lifting of the arntcauses it to liftthe front end of tumbler D, as shown in Fig. 3, and the incline b is ofsuliicient pitch to cause arm 0 to rise sufficiently to lift the tumblerD until the arm can pass below the latter,which, after the arm haspassed, drops, and the jaw is locked thereby, as indicated in Fig. 4.

In my application and patent above referred to, the end of the arm isbeveled and adapted to wedge under the tumbler and lift the lattersimilarly to the manner in which the jaw is lifted by the incline I), asabove described. In the present case, however, it should be observedthat the lifting of the tumbler is accomplished by the vertical movementof the arm alone, not by its horizontal movement, so that there is nostrain or push exerted on the pivots of the tumbler, as is the casewhere bevels are employed, as in my application above referred to. Thisfact will be particularly observable by reference to Fi 2, 2-3, andel,where the horizontal top surface of the end of arm C only contactswith the horizontal under surface of the angular shoulder of thetumbler, and not with the vertical faces thereof. For this reason theface of the tumbler need not be beveled at all, but might be perfectlyangular were it not desirable to provide forcouplin g with alink-aml-pin coupler. For this reason the end face of the tumbler may berounded, and not for the purpose of serving as an incline to cause thetumbler to ride up on the entering end of the arm.

To uncouple, the tumbler D is oscillated by link E, lifting its frontend sufficiently to permit arm C to escape tl'lerefrom, the incline b,which supports the entire weight of the jaw and arm so long as thelatter are coupled, causin the jaw to swing open by gravity until theincline is disengaged from the shoulder.

Having described my iuventiomwh at I claim as new is- 1. In acar-coupling, the combination of a tumbler having an angular front face,with a swinging hook having an arm adapted to enter the mouth of thedraw-bar when closed and also having an incline at the junction of thearm and shank of the hook adapted to cause the hook and arm to risevertically when the hook is closed or the arm swung imvard,whereby theend of the arm as it moves under the angular face of the tumbler liftsthe tumbler solely by its vertical movement alone, and the use of andnecessity for inclined faces on the end of the arm and face of thetumbler are obviated, all substantially as specified.

2. The combination, in a coupler of the ch ar acter described, of atumbler pivoted in the throat of the d raw-bar and having an angularfront face, with the swinging hook B, its arm 0, adapted to enter themouth of the draw-bar, having a shoulder, c, at its end to engage thetumbler, and the incline b at the junction of the arm with the shankofthe hook, adapted to engage the mouth of the draw-bar and lift the hookand arm vertically as the latter is swung inward,whereby the lifting ofthe tumbler is effected without the employment of coacting inclinedfaces on the tumbler or arm, substantially as described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
